I am trying to prove E(kin)=(3/2)RT (T in kelvin) in order to prove pV=nRT (so i cant use that equation) I have proved E(kin)=(1/2)mv^2

    Can you use the formula for rms velocity? You directly get the results if you use it.

    v= sqrt(3RT/M) if you substitute this m cancels and you get 3RT/2. I don;t have any links...

Can you show the other way around?

    i have been trying on this for some while. Since I am a lousy statistician only had one course with medicore results i have no idea about root mean square to start with. But my question is is it possible to derive root mean square formula for speed from the math formula that is since you brought up the root mean formula:)
